Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 已修复 Linux 内核中的下列漏洞：tracing: Avoid NULL return from hist_field_name() on truncation hist_field_name() returns everywhere except the fully-qualified VAR_REF/EXPR case, where snprintf() truncation returns NULL early and bypasses the bottom NULL-> guard.
    Callers don't expect NULL: strcat(expr, hist_field_name(field, 0)) at trace_events_hist.c:1758 and the strcmp() in the sort-key match loop at :4804 both deref it. system and event_name are bounded by MAX_EVENT_NAME_LEN, but the field name on a VAR_REF is kstrdup'd from a histogram variable name parsed out of the trigger string and has no length cap, so a long enough var name in a fully qualified reference can reach the truncation path. Keep the length check but leave field_name as on overflow. (CVE-2026-64028)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: tracing: Avoid NULL return from     hist_field_name() on truncation hist_field_name() returns  everywhere except the fully-qualified     VAR_REF/EXPR case, where snprintf() truncation returns NULL early and bypasses the bottom NULL-> guard.
    Callers don't expect NULL: strcat(expr, hist_field_name(field, 0)) at trace_events_hist.c:1758 and the     strcmp() in the sort-key match loop at :4804 both deref it. system and event_name are bounded by     MAX_EVENT_NAME_LEN, but the field name on a VAR_REF is kstrdup'd from a histogram variable name parsed out     of the trigger string and has no length cap, so a long enough var name in a fully qualified reference can     reach the truncation path. Keep the length check but leave field_name as  on overflow. (CVE-2026-64028)

Note that Nessus relies on the presence of the package as reported by the vendor.
